would be 36 cents for a 24 hour day based on a utility rate of 8.3 cents per kilowatt hour. bathroom floor with an electric radiant floor heating mat generating 12 Watts per S.F. You should not expect noticeable savings if you install warm floors only in small areas of your home.Īssuming there are no savings, the cost to run radiant floor heating in a 15 S.F.

According to ASHRAE (standard 55-1992) for each 1 degree F that you set your thermostat lower, you will reduce your heating bill 4-5%. This reduces your energy costs substantially. Forced air systems must be set at 75☏ to feel this warm, whereas with radiant floor heating, you can set your thermostat to 66☏ and feel comfortable. For example, the American Society of Heating, Refrigeration and Air-conditioning Engineers (ASHRAE) reports a "comfortable" temperature is 70☏. Numerous publications point out that radiant floor heating systems create sufficient thermal comfort with the thermostat set 5-7☏ lower than forced-air heating systems. The natural response is to compensate for the discomfort by setting the central thermostat at a higher temperature. Forced-air heating systems create ascending air flow that concentrates the warmth in the upper part of the room (at the head level) leaving the feet cold. There is no such heat loss with electric radiant floors. ![]() The warm air loses heat on its way requiring additional energy expenditure. Forced-air heating systems need energy to warm the air and to supply a blower, which forces the air through filters and air ducts. Numerous analyses and publications confirm that electric radiant floor heating is more likely to save money on your heating bill compared to conventional forced-air heating systems. Typically, electric radiant floor heating will not increase your heating bill. SeptemWHAT ABOUT THE COST OF RADIANT FLOOR HEAT? What About The Cost Of Radiant Floor Heat.
